The 29-year-old is a free agent, having been released last summer by Leicester City, and will provide Easter Road boss Alan Stubbs with additional cover for the club’s Scottish Cup semi-final against Dundee United, as No.1 Mark Oxley is suspended for the trip to Hampden.
While Finnish stopper Otso Virtanen is likely to take over for that match, Stubbs would only have teenager Sean Brennan as back-up.
Logan, originally from County Donegal in the Republic of Ireland, joined Leicester City as a promising 15-year-old. He was, however, unable to establish himself as a first-team regular with the Foxes, spending much of his career on loan at clubs such as Boston United, Stockport County, Luton Town, Bristol Rovers, Rotherham United and Rochdale.
Hibs head coach Alan Stubbs told the Evening News: “Conrad will bring invaluable experience at an important time of the season.”
